There's no such option in 2.x, but you can make a hack.

For guests:
Set a cookie to the user, read this cookie in stub file and change the $skin value to the one from cookie.

For users:
Save skin name in user settings and then use this value in stub file for $skin variable.

$skin = 'custom';

ot: nice design (:

Thank you very much for your answer.
But, i'm afraid, i doesn't understand how to set a cookie and read it in stub file. Actualy, stub file as always make me crazy ... :-/
Well ... i think it will be too difficult for me.

Shall i set a link, whitch run anyone on lighter skin ? For instance, on top menu, "Lighter skin", and run blog with this one ?

So, i've made a_stub file, and then i can change skin, anyone could click and see lighter blog, but problem is, when you click on read more, the original skin is displaying.
Same think when you want to write a comment.

How should i do now ? :-/ (sorry for my english) ...

I'll try to make a hack or plugin

Wonderful !
Nice idea ! :)

Enabled cross posting across multiple blogs (a file edit is required but I don't know which one off the top of my head), have the same list of categories in two blogs (like "sports" and "sports 2" for example, always post in matching categories in both blogs, and select the dark skin for the first blog and the light skin for the second blog. :)
